The signals are stored as interleaved binary samples.  If you want to
do something with them outside of gnuradio, the easiest way is to use
octave/matlab :

Otherwise, you can use the scripts provided in that link as a guide to
write your own code to get the samples into whatever system you want
(c++, mathematica, whatever).
